Abstract: An organic light-emitting display apparatus, including a substrate including a plurality of pixel areas and non-pixel areas in a display area, a plurality of pixel electrodes respectively corresponding to the plurality of pixel areas, a pixel-defining layer including a cover portion and openings, wherein the cover portion covers an edge of each of the plurality of pixel electrodes, and each of the openings exposes a central portion of a pixel electrode among the plurality of pixel electrodes, an auxiliary electrode located such that the auxiliary electrode corresponds to at least a portion of a top surface of the cover portion, and an intermediate layer and a counter electrode, each located in the openings. The pixel-defining layer may have an under-cut structure in which the at least a portion of the top surface of the cover portion is recessed from the auxiliary electrode.
